BACKGROUND OF THE INVENTION

The present invention relates to a desk assembly and, more particularly,to a desk assembly including a main desk and an auxiliary desk.

Office desks are a necessity in ordinary offices for placing books,documents, and stationery as well as computer screens, keyboards,mousse, and printers so that the users can read, write, or work easily.

FIG. 7 shows a conventional office desk including a main desk A and aside desk B. An end of the side desk B is fixed by a bracket C to abottom of the main desk A. A longitudinal side of the side desk B isperpendicular to a longitudinal side of the main desk A, such that theoffice desk is substantially L-shaped. A user can read, write, or workon the main desk A and can use the side desk B when discussing with acoworker or for other purposes. However, the side desk B is fixedrelative to the main desk A and, thus, can not move into a space belowthe main desk A when not in use. Thus, the office desk occupies aconsiderable space.

Thus, a need exists for a novel desk assembly that occupies a smallerspace when not in use.

BRIEF SUMMARY OF THE INVENTION

A desk assembly according to the present invention includes a main deskhaving a top board. A rail is mounted to a bottom side of the top boardof the main desk and has a longitudinal direction. The rail includes atrack extending in the longitudinal direction of the rail. A rotationalseat includes a top and a bottom. A slider is fixed to the top of therotational seat and slideably received in the track. The rotational isseat slideable along the track in the longitudinal direction of therail. An auxiliary desk includes a top board having a top face mountedto the bottom of the rotational seat. The auxiliary desk is rotatablerelative to the main desk. The auxiliary desk and the rotational seatare jointly moveable relative to the main desk in the longitudinaldirection of the rail.

When not in use, the auxiliary desk can be rotated to a position belowthe main desk to save space. Furthermore, the auxiliary desk can berotated to a position at a desired angle to the main desk.

The present invention will become clearer in light of the followingdetailed description of illustrative embodiments of this inventiondescribed in connection with the drawings.

DETAILED DESCRIPTION OF THE INVENTION

With reference to FIGS. 1-3, a desk assembly according to the presentinvention includes a main desk 1 and an auxiliary desk 2. A rotationalseat 3 is mounted between the main desk 1 and the auxiliary desk 2, sothat the auxiliary desk 2 can rotate relative to the main desk 1 about arotating axis defined by the rotational seat 3.

Thus, when the auxiliary desk 2 is not in use, the auxiliary desk 2 canbe moved to a position below a top board 11 of the main desk 1 to savespace. On the other hand, when using the auxiliary desk 2, the auxiliarydesk 2 can be rotated to a position at a desired angle to the top board11 of the main desk 1, providing convenient use.

With reference to FIGS. 2, 2A, 2B, 3, and 4, a bottom of the rotationalseat 3 is fixed by screws 31 to a top face of the top board 21 of theauxiliary desk 2. In the form shown, two parallel rails 4 are mounted toa bottom side of the top board 11 of the main desk 1. Each rail 4includes a track 41 extending in a longitudinal direction of the rail 4.A slider 32 is fixed to each of four corners of a top of the rotationalseat 3. Each pair of sliders 32 is slideably received in one of thetracks 41 in the longitudinal direction of the rails 4. Thus, thepivotal seat 3 can reciprocatingly slide relative to the main desk 1 inthe longitudinal direction of the rails 4. However, the main desk 1 caninclude only one rail 4, and the rotational seat 3 can include only oneslider 32.

By such an arrangement, the auxiliary desk 2 can move in a wider rangerelative to the main desk 1, allowing more spatial combinations of theauxiliary desk 2 and the main desk 1. Namely, the auxiliary desk 2 isrotatable relative to the main desk 1, and the auxiliary desk 2 and therotational seat 3 are jointly moveable relative to the main desk 1 inthe longitudinal direction of the rails 4. In an example shown in FIG.1, the auxiliary desk 2 is moved to a left side of and perpendicular tothe main desk 1. In another example shown in FIG. 4, the auxiliary desk2 is moved to a right side of and perpendicular to the main desk 1. In afurther example shown in FIG. 5, the auxiliary desk 2 is moved to theright side of the main desk 1, and a longitudinal side of the top board21 of the auxiliary desk 2 is parallel to a longitudinal side of themain desk 1. The main desk 1 and the auxiliary desk 2 can have relativepositions other than those shown.

With reference to FIGS. 2, 6, and 6A, the auxiliary desk 2 includes onlytwo legs 22. Each leg 22 has an upper end mounted by a hinge 23 to thetop board 21 of the auxiliary desk 2, allowing the legs 22 to be foldedby pivoting the legs 22 towards the bottom face of the auxiliary desk 2.Each hinge 23 can include an elastic element (not shown) to bias eachleg 22 to an extended, upright position or a folded, horizontalposition. The hinges 23 can be of a conventional type.

In the form shown, the main desk 1 includes four legs each having anupper end mounted to the bottom side of the top board 11. When not inuse, the auxiliary desk 2 can be moved into a space below the top board11 of the main desk 1. Furthermore, the legs 22 of the auxiliary desk 2can be pivoted to the folded position adjacent to the bottom face of thetop board 21 of the auxiliary desk 2. Thus, the user can move his or herlegs without interference from the legs 22 of the auxiliary desk 2.Furthermore, moving the legs 22 to the folded position adjacent to thebottom face of the top board 21 of the auxiliary desk 2 providesaesthetically pleasing effect. Further, the legs 22 can be connected bya rod 221. An L-shaped retaining rod 24 is rotatably mounted to thebottom face of the top board 21 of the auxiliary desk 2. The L-shapedretaining rod 24 can be rotated to a position supporting the rod 221when the legs 22 are in the folded position (FIG. 6B). Thus, the legs 22can be reliably retained in the folded position adjacent to the bottomface of the top board 21 of the auxiliary desk 2.

With reference to FIGS. 2 and 6, a cover plate 12 mounted by a hinge 13to each of four edges of the top board 11 of the main desk 1. Each coverplate 12 can be pivoted inward to a horizontal position adjacent to thebottom side of the top board 11 of the main desk 1 or pivoted outward toan upright position. Each hinge 13 can include an elastic element (notshown) to bias each leg 13 to the upright position or the horizontalposition. The hinges 13 can be of a conventional type. However, the maindesk 1 can include only one cover plate 12 mounted to one of the fouredges.

With reference to FIG. 1, when the auxiliary desk 2 is completelyreceived in the space below the top board 11 of the main desk 1, thecover plates 12 are moved to the upright position for shieldingpurposes, such that the user is less likely to touch the auxiliary desk2 and the legs 22 while providing aesthetically pleasing effect. When itis desired to use or move the auxiliary desk 2, the cover plates 12 aremoved to the horizontal positions adjacent to the bottom side of the topboard 11 of the main desk 1 to avoid interference to the main desk 1.

With reference to FIG. 1, a frame 11 is placed on a top side of the topboard 11 and define two compartments 141 for receiving 3C electronicproducts, such as an iphone, ipad, or notebook (not shown), preventingfalling of these objects.

Although specific embodiments have been illustrated and described,numerous modifications and variations are still possible withoutdeparting from the essence of the invention. The scope of the inventionis limited by the accompanying claims.
